PATENT CHARLES R. BROWN, OF IMPERIAL, AS SIGNOR OF ONE-HALF TO XVILLIAMMCCREERY, OF PITTSBURG, PENNSYLVANIA.

CABLE-MOTOR.

SPECIFICATION forming part of letters Patent No. 291,144 dated January1', 1884,

Application filed September 7,1883. (No model.)

To all whom it may concern:

Be it known that I, CHARLES R. BROWN, of Imperial, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Gable-Motors; and I do hereby declare the following to bea full, clear, and exactdescription thereof.

My invention relates to an improvement in devices for connecting a caror train of cars with a traveling band or cable in such a manner thatthe car may be caused to travel with the cable or stopped at any desiredpoint without interfering with the traveling motion of the cable; and itconsists in one or more wheels mounted on the car, around which wheelsthe traveling cable passes, said wheels having cable and brake-bandgrooves, in combination with brake-bands and mechanism for releasing thebrake-bands or tightening the same, for

locking the wheels so asto prevent them from turning on their axles,when, owing to the friction between the cable and the periphery of thewheels, the car is caused to travelwith the cable or'band.

I will now describe my invention, so that others skilled in the art maymanufacture and use the same, reference being had to the accompanyingdrawings, forming a part of this specification, in which' Figure 1 is aside elevation of my improved device. Fig. 2 is a plan view of' thesame. Fig. 3 is a side'elevation of the band-wheels, brake, and cable.Fig. 4 is a view illustrating the brake or locking device. Fig. 5 is across-section through the line at m, Fig. 2. Fig. 6 is a Viewillustrating the position of the ca ble around the band-wheels.

Like letters of reference indicate like parts wherever they occur.

In the drawings my invention is shown adapted for drawing coalcars, thecable a passing over the train of cars and around two bandwheels, b c,which are situated in a line with each other and the cable a, and arejournaled in suitable bearings on the car d. On

the periphery of these wheels are grooves e for the reception of thecable, which cable passes first above the wheel b, around the frontportion of the periphery of the wheel 0, back under the wheel, to andaround the rear portion of the periphery of the wheel b, and

thence forward above the wheel 0, in a line with the direction of itsapproach to the car. On the periphery of the wheels I) and c are othergrooves, h and z, around which are 5 5 placed loops or bands j k, whichare secured or fastened to opposite sides. of the rod or cylinder Z,which rod extends transversely across the car between thewhecls b and 0,so that by turning the rod on its axis the bands to j and k are eitherloosened,so as to permit the rotation of the wheels b and c, or aredrawn down in the grooves h and i around the wheels b and c, and beartightly against the same, so

as to lock the wheels I) and c and prevent them 6 5 from turning.

At one end of the rod Zis a lever, m, extending along the side of thecar, so that by pressing the lever down the rod is caused to turn. Theend of the lever, when so lowered, 7c is held in position by the teethof the ratchet n.

The operation is as follows: The cable a, traveling over the wheels I)and 0, causes them to revolve on their axes, and the car 0 remainsstationary. In order to put the car in motion, 7 5' the lever m ispressed down, which turns the rod or cylinder Z, and draws the bands jand k tight in the grooves 7L and i, and, owing to the friction betweenthe bands and the grooves, the wheels I) and c are locked or prevented80 from turning. The cable a, continuing to travel, and, owing to thefriction, being prevented from slipping over the grooves e, car= riesthe car (1 with it over the track 0. In order to stop the car, it issimply necessary to 8 5' unlock the wheels I) and c by releasing thelever 111., when the wheels b and 0 will again re volve, and the car (Zwill remain at rest.

The advantages of my invention are, owing to the friction-brake and thefriction attacho ment of the cable to the car, injury to the cable orcar is prevented from suddenly starting or stopping the same, and alsothat the car is easily and rapidly started or stopped. This car (I iscoupled with trains of cars, and acts 5 as a motor therefor.

Although I have described two drivingwheels, I; and c, and a certain wayof connecting them with the cable, I do notvdesire to limit myself tothe same, as a single wheel 100 may be substituted therefor, and thecable may be passed first completely around the pe= riphery of the wheelI), and then around the wheel 0; or more than two wheels may be ourployed, thereby increasing the friction.

My improved device may also be difl'erently arranged on the car, as byplacing it under the car instead of in the manner described.

Having thus described myinvention, whatI claim, and desire to secure byLetters Patent, 1s

1. In combination with an endless cable, a car having mounted thereon arevolving wheel provided with a cable-groove and a brake-band groove, abrakcband arranged in the brake-groove of the wheel, and mechanism fortightening and loosening the brake-baud, substantially as and for thepurposes specified.

2. The combination, with a car or truck adapted to be driven by anendless band or cable, of two revolving wheels mounted on the car, eachof said wheels having a cablegroove, two brake-bands one arranged aroundeach of said wheels, and a rotating shaft arranged betwcen the wheels,and to which the brake-bands are secured, substantially as and for thepurposes specified.

In testimony whereof I have hereunto set my hand this 29th day ofAugust, A. D. 1883.
